▎ 摘　　要

NOVELTY - Preparing reductive graphene oxide comprises (i) mixing graphene oxide and water, subjecting to ultrasonic peeling to obtain graphene oxide mixture liquid; and (ii) mixing graphene oxide mixture liquid and ethylenediamine disuccinic acid and carrying out reduction reaction under microwave radiation to obtain reductive graphene oxide. USE - The method is useful for treating waste water containing antibiotics (claimed). ADVANTAGE - The method is simple, easy, economical and environmentally friendly; has mild reaction conditions, good short adsorption capacity; can reuse ethylenediamine disuccinic acid; produces product with low surface oxygen-containing functional group, good dispersibility and large surface area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) reductive graphene oxide, prepared as mentioned above; (2) use of reductive graphene oxide in treating waste water containing antibiotic; and (3) use method of reductive graphene oxide, comprising mixing reductive graphene oxide (0.08-0.8 g/l) and wastewater containing antibiotic, carrying out oscillating adsorption reaction and completing antibiotic-containing wastewater treatment.
